基于拆接线表自动生成和校核的屏柜改造方法研究

The research on a method for automatically generating and verifying screen cabinet modifications based on a cable disconnection table

针对当前变电站屏柜改造中手动绘制拆线表以及根据设计院图样手动绘制接线表效率低下、人工验证接线表正确性较低的问题,提出了一种基于拆接线表自动生成和校核的屏柜改造方法。首先通过解析改造后屏柜二次回路模型,获取改造后屏柜的外部线缆接线关系,进而自动生成拆线表。接着,系统识别改造后的端子排图样,获取屏柜改造后的外部线缆接线关系,自动生成改造后的接线表。根据装置型号将接线表与接线表模板进行防误校验并生成校验结果,确保端子排接线功能正确。在实际工作现场,按照无异常的接线表进行二次接线,并自动调整回路模型文件。本研究对于电力系统改造领域具有重要意义,为变电站屏柜改造提供了一种有效的方法和技术支持。

This paper addresses the inefficiency in manually crafting disconnection schedules and wiring diagrams for substation cabinet renovations.It introduces a method for cabinet refurbishment based on the automatic generation and verification of disconnection schedules.Concurrently,the method is designed to alleviate the issue of lower accuracy in manually verifying the correctness of wiring diagrams.Initially,the system obtains and parses the model of the secondary circuit post-screen cabinet renovation,enabling it to discern the external cable connection relationships.Subsequently,it auto-generates the disassembly table.The system then identifies and extracts the external cable connection relationships from the renovated terminal strip drawing,leading to the automatic generation of the wiring table post-renovation.To ensure error prevention,the wiring table is crosschecked against an established template.Verification outcomes are produced,guaranteeing the accuracy of terminal strip connections.In real-world applications,the secondary wiring aligns with the standard wiring table,and the circuit model file undergoes automatic adjustments.This research offers significant implications for power system renovations,offering an efficacious method and robust technical support for substation screen cabinet refurbishment.
